Base-induced intramolecularcyclization of novel (4-aryl-2,4-dioxobutyl)methylphenylsulfonium salts prepared from the commercially available 1-arylethanone by a cost-effective process is described in this paper. The reaction was completed within 10 min to produce a family of 2-unsubstituted 5-aryl-3(2H)-furanones in excellent yield. This procedure is simple, and can be carried out under mild conditions

efficient strategy towardconjugated arylbuta-1,3-diynyl sulfides (Ar–C≡C–C≡C–SR) was herein reported. In the newly developed one-pot, three-steps protocol, the synthetically or materially significant arylbuta-1,3-diynyl sulfides were obtained from easily accessible 4-hydrocarbylthio-1-arylbuta-1,3-diones, avoiding usage of expensive terminal aryl acetylenes as substrates or any transition metal complexes
